About event logging for backup and restore

What event
logging is  

Data ONTAP automatically logs significant events and the times at which they occur during dump and restore operations. All dump and restore events are recorded in a log file named backup in the /etc/log/ directory. Event logging is turned on by default.

Reasons for viewing event log files  

You might want to view event log files for the following reasons:

• To find out whether a nightly backup was successful
• To gather statistics on backup operations
• To use information contained in past event log files to help diagnose problems with dump and restore operations

Log file rotation  

Once every week, the log files are rotated. The /etc/log/backup file is copied to /etc/log/backup.0, the /etc/log/backup.0 file is copied to /etc/log/backup.1, and so on. The system saves the log files for up to six weeks; therefore, you can have up to seven message files (/etc/log/backup.0 through /etc/log/backup.5 and the current /etc/log/backup file).

Event log files in takeover mode  

If a takeover occurs in a cluster, the set of backup log files for the takeover filer remains separate from the backup log files for the failed filer.
